Inventory Manager API · events
Replay committed events at-or-after since (a journal sequence number), oldest first
GET /events
Use to catch up before subscribing to /events/stream. One response is a page: limit defaults to 500 and is capped at 5000 (an over-cap request is clamped). Pages are sequence-ordered and the boundary is stable — repeat with since=<last event's sequence + 1> until a page comes back smaller than limit to replay the journal exactly once. upTo (inclusive) ends the replay at a sequence instead of the journal's head — with GET /events/head it replays the journal as it stood at a moment. Appends nothing: a read of facts already journalled.
Access
Requires stock:read or products:read or catalogs:read or locations:read.
Any one of these scopes is enough.
How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.
AI agent tool
No agent tool. The journal replay a consumer pages through to build its projection; agents read the projections the list and get tools serve, and the audit trail (audit_trail) for history.
Connecting an agent: AI agents.
Example
curl -X GET 'https://inventory.getmanifold.io/events?since=1042&limit=500' \
-H "Authorization: Bearer $MANIFOLD_TOKEN"const response = await fetch("https://inventory.getmanifold.io/events?since=1042&limit=500", {
method: "GET",
headers: { Authorization: `Bearer ${process.env.MANIFOLD_TOKEN}` },
});
if (!response.ok) throw new Error(`${response.status}: ${await response.text()}`);
const answer = await response.json();[

]The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web
page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: inventory-manager.openapi.json. Base URL https://inventory.getmanifold.io.
Errors
Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.
